Surface flux intercomparison between the MM5 model and observations during the storm-scale observations regional measurement program - fronts experiment systems test 1992
- National Center for Atmospheric Research, Boulder, CO (United States)
Mesoscale model 5 (MM5) is being used as a data assimilation tool for the Atmospheric Radiation Measurement (ARM) Program. There is a need to verify that the model physics is consistent with observations under a range of conditions. Surface fluxes of heat, moisture, and momentum are a particular area of uncertainty in the model owing to their dependence on surface properties, some of which are time-dependent. The National Center for Atmospheric Research (NCAR) Atmosphere-Surface Turbulent Exchange Research (ASTER) facility provides direct measurements of the fluxes near the surface by means of three-dimensional sonic anemometers collocated with fast-response temperature and humidity sensors. Additionally aircraft data from a low-flying King aircraft have been taken over the ASTER site. The primary objective is to detect any systematic errors in the MM5 surface flux formulation that could have adverse effects on the model data assimilation and, thence, to suggest corrections that help avoid such inaccuracies.
